NCT06684405

Brief Summary

The goal of this trial is to investigate whether low daily doses of fluoridated milk, in addition to oral hygiene routines with fluoridated toothpaste, can prevent caries development in adolescents' teeth. The main questions it aims to answer are:

  • Does fluoridated milk lower the number of caries lesions in teeth over time?
  • Does fluoridated milk lower the number of enamel caries lesions over time? Researchers will compare an intervention group receiving doses of fluoride in water to add to milk and a control group receiving water to add to milk. The 12-13 year participants will:
  • be examined at a baseline and once yearly up to 2 years
  • be provided directly with the doses every second month at their dental clinic
  • take the fluid daily

Outcome Measures

Primary Outcomes (1)

  • Caries development in enamel and dentine

    caries increment measured as change/no change of DMFS (Decayed, Missing, Filled, Surfaces)

    From enrollment to the end of intervention at 2 years

Secondary Outcomes (2)

  • Caries lesion arrest

    From enrollment to the end of intervention at 2 years

  • Caries lesion progression

    From enrollment to the end of intervention at 2 years

Study Arms (2)

Intervention

ACTIVE COMPARATOR

The subjects in the intervention group received individually packaged daily doses of sodium fluoride solution in 0.5 ml sterile water to be added to 200 ml of milk

Dietary Supplement: sodium sodium fluoride solution (0.75 mg for subjects aged 12 and 1.0 mg for subjects aged 13)

Control group

PLACEBO COMPARATOR

Subjects in the control group received a daily dose of 0.5 ml sterile water to be added to 200 ml of milk.

Dietary Supplement: Subjects in the control group received a daily dose of 0.5 ml sterile water to be added to 200 ml of milk.

Masking Details
The subjects and their parents/guardians, the clinicians performing the examinations, the staff-members delivering the packages with solutions to the subjects, the trial investigators and the outcome assessors were blind to the allocation and group assignment. The solutions were distributed to the subjects in tubes pre-labelled with code numbers. The tubes had the same design independent of the solution with fluoride or placebo. After the randomization, lists with code numbers were saved as sealed files in a safety-deposit box. The code was broken when the study was completed, and the assessment of the outcome measures were processed.
